" distinguish the friend from the manipulator? The answer is simple: the true teacher is not the one who teaches us the ideal path, but the one who shows us the many ways of reaching the path that we need to travel if we are to find our destiny. Once we have found that path, the teacher cannot help us anymore, because its challenges are unique. This applies to neither love nor war, but unless we understand it, we will never get anywhere. "
